CHAPTER 4

AIRCRAFT STORAGE AND SHIPMENT

4-1. General. The following paragraphs provide information on the preparation of Army aircraft for shipment and storage.

4-2. Categories of Storage. The length of time that the aircraft will be inactive will determine which of the following categories of storage will be used.

a. Flyable Storage. Flyable storage is the prescribed procedure to maintain a stored aircraft in operable condition. Next to daily use, this category of storage keeps the aircraft in the best possible condition.

All scheduled preventative maintenance will be performed on aircraft in flyable storage, and periodic operation of the aircraft and all systems is required. There is no time limit on flyable storage.

b. Short Term Storage. Short term storage is used to store an aircraft for a period not to exceed 45 days. Aircraft in short term storage require extensive preservation but very little periodic attention.

c. Intermediate Storage. Intermediate storage is used to store aircraft for a period of 46 to 180 days.

Aircraft in intermediate storage require very extensive preservation but minimal periodic attention.

d. Long Term Storage. Procedures for long term storage are not available for the storage of Army aircraft if storage beyond 180 days is required, the aircraft will be depreserved, returned to flyable status, operated, and represerved in accordance with this chapter.

4-3. Responsibility. The Commanding Officer shall be responsible for initiating action to place aircraft in storage in accordance with this chapter. The type of storage used shall be selected based on the length of time the aircraft will be inactive.

4-4. Preparation of Aircraft for Storage. When the decision is made to place aircraft in flyable, short term, or intermediate storage, the aircraft will be prepared in accordance with the applicable Aviation Unit Maintenance (AVUM) technical manuals. Authorization to take deviation from published procedures will be obtained, in writing, from Commander, U S. Army Aviation Systems Command, ATTN AMSAV-SDP, 4300 Goodfellow Blvd, St Louis, MO 63120-1798.

4-5. Inspection of Stored Aircraft. All aircraft placed in storage shall be carefully inspected at regular intervals of 60 days or less, depending on local conditions. Stored aircraft shall be corrosion-treated if this precaution is found necessary when conducting inspection for corrosion. Particular attention shall be given to those areas where moisture deposits will not evaporate rapidly.

Normally, corrosion will not be as prevalent on painted surfaces as on unpainted surfaces. The commanding officer of the storage facilities shall be responsible for establishing a program of periodic inspections of stored aircraft in addition to the prescribed inspections listed below.

a. Ensure proper preservation and ventilation of aircraft and take immediate action to correct all unsatisfactory conditions.

b. Ensure drainage holes on underside of fuselage, wing, center section, and control surfaces remain unobstructed.

c. When canvas covers are used for protection, they shall have drainage holes installed at locations where water would tend to accumulate.

d. During hot weather, spot checks shall be made among each type and model of stored aircraft to determine maximum interior temperatures encountered.

This shall be accomplished by hanging a standard thermometer in the interior of aircraft, and recording readings during the hottest parts of day. When temperature exceeds 160°F (71°C), action shall be taken to ventilate aircraft.

e. To aid ventilation on aircraft employing astrodomes, astrodome may be removed and replaced with a covered flue.

f. Forced ventilation may be employed when other methods of ventilation are not adequate to prevent sweating in interior of aircraft and resulting accumulation of condensation and mildew.

g. Exterior locks, ground wires, chocks, mooring ropes, rods, and eyes shall be inspected every 30 days and immediately after aircraft has been subjected to high velocity winds (exceeding 40 mph). Pulled rods or

TM 1-1500-204-23-1

deteriorated locks, ground wires, chocks, mooring ropes, and rods shall be replaced.

NOTE

Under some conditions, corrosion may attack the metal through the paint. In such cases, the affected areas will be indicated by blisters or a scaly appearance of the paint.

4-6. Maintenance of Stored Aircraft. Precautions shall be taken to ensure that adequate maintenance will be accomplished to maintain the aircraft in the proper state of preservation in accordance with applicable aircraft maintenance manual. For aircraft in flyable storage, calendar and dual criteria inspections will be completed as they become due.

4-7. Entries In Aircraft Forms. When an aircraft is placed in storage, process DA Form 2408 series forms in accordance with DA PAM 738-751. Include an entry indicating the type of storage, the date placed in storage, and the date represervation is due.

4-8. Removal of Aircraft from Storage. When an aircraft is removed from storage, the inspection and maintenance performed will be dependent on the type of storage the aircraft has been in.

a. Depreservation. Depreserve aircraft in accordance with applicable AVUM technical manuals.

b. Inspection. Perform preventative maintenance daily inspection and all calendar and dual criteria inspections that are due.

c. Maintenance. Correct aircraft deficiencies as required.

d. Operational Check. Perform Maintenance Operational Check (MOC) and/or Maintenance Test Flight (MTF) as required in accordance with TM 55-1500-328- 25.

4-9. Shipment of Aircraft. Step by step procedures for the preparation, loading, tiedown, and unloading of Army aircraft for shipment by vessel, truck, and cargo aircraft are provided in the Preparation for Shipment Manual applicable to the aircraft. Authority to take deviation from the procedures in the applicable Preparation for Shipment Manual must be obtained, in writing, from Commander, U.

S. Army Aviation Systems Command, ATTN. AMSAV- SDP, 4300 Goodfellow Blvd, St. Louis, MO 63120-1798, AUTOVON 693-2372, Commercial (314) 263-2372.

4-10. Preservation and Packaging of Aircraft Components. General information on the preservation and packaging of Army materiel is provided by TM 746- 10, Marking, Packaging and Shipment of Supplies and Equipment: General Packaging Instructions for Field Units Detailed information is provided by TM 38-230-1 and TM 38-230-2, Preservation of Materiel Preservation, Volumes I and II, respectively.

a. Special Reusable Containers. Preservation and packaging instructions for major aircraft components that have special reusable containers are contained in the applicable Aviation Unit Maintenance (AVUM) Technical Manual.

b. Packaging Procedures. Aircraft components will normally be shipped in the same packaging the replacement component was received in. When this is not possible and assistance is required in determining the preservation and packaging of a specific component, contact Commander, U. S. Army Aviation Systems Command, ATTN. AMSAV-SDP, 4300 Goodfellow Blvd, St Louis, MO 63120-1798.
